Valve for 8D and 4D Batteries Push-in Style with 3/4" vent openings.
**Our valves do not fit into tapered cell batteries which are commonly found in 4D & 8D batteries.

5 YEAR WARRANTY -The valves are warranted for a full five years (fast charge for three years). If a valve causes a cell failure due to a manufacturing defect, the valve and the cell will be repaired or replaced.
FASTER - Water flows through a single connection filling each battery set accurately, eliminating all the guesswork. Our innovative push-in valves make installation of pre-strung systems fast and easy.
SAFER - The internal working components of the valve are above the cells, keeping them out of the electrolyte. The level indicator eye verifies proper valve operation.
BETTER - Battery Watering Technologies’ valves add the correct amount of water every time. With proper battery maintenance, you can add years to the life of your batteries.
